File Nos. BC -1407.08, GAH-0207
Dear Mr. Helms:
Attached is a description of the environmental monitoring program which Duke
Power Company has agreed to implement in Belews Lake and the Dan River in
conjunction with the proposed relocation of the Belews Creek Steam Station
ash basin effluent discharge (please refer to Mr. W 0 Parker's letter of
December 8, 1981). This program has been developed in accordance with discuss-
ions between Duke and DEM staff on August 25 and December 17, 1982.
Duke understands that implementation of this program will be required as a
condition of issuance of the requested modification of the Belews Creek NPDES
permit. We also understand that: a) Duke and North Carolina will schedule
review meetings to discuss results of the various program phases within six
months of completion of each phase, with a minimum of one such meeting per
calendar year; and b) a report shall be prepared by Duke and supplied to
North Carolina for each such review meeting; and c) a.ny studies or monitor-
ing performed by Duke, beyond the explicitly stated items in the program, which
relate to impacts of Belews Creek Steam Station discharges in Belews Lake or
the Dan River will also be made available to the Division staff for review and
evaluation as a part of the overall program.
Duke feels that the work plan which has been developed will
demonstrate that conditions protective of water quality in
being met. We look forward to continuing our work with DEM
Sincerely,
S B Hager, Chief Engineer

BELEWS LAKE/DAN RIVER MONITORING.PROGRAM
DUKE POWER COMPANY
CHARLOTTE, NORTH CAROLINA
DECEMBER 20, 1982
General Procedures and Provisions:
This.monitoring program includes provisions for collection, analysis, and
reporting *of data to demonstrate that conditions protective of water quality
in the Dan'River and in Belews Lake.are being met with regard to NPDES-
permitted ash basin effluent discharges from Duke's Belews Creek Steam
Sta t.i on.
Duke Power.Company will prepare a report describing the results.of each
program phase, supply the report to'the North Carolina Division of Environ-
mental Management, and schedule a meeting with the Division staff for review
and discussion purposes within six months cf the completion of each phase.
In addition, any other studies or monitoring performed by Duke which relate
to the impacts -of Belews Creek Steam Station discharges in Belews Lake or
the Dan River will be made available to the Division for review and evaluation
as a part of the overall program.
